To all whom it may concern/.

Be it known that I, SIGURD WILLIAM EK- ROOS, a subject of the Czar of Russia, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful 1m rovements in Looks for Window- Sash'; an I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others I0 skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in looks for window sas'h and comprises a pivotal lever mounted upon a plate adapted to be fastened to one sash of a window and provided with a buffer at the end 2'0 thereof and in the provision of means for holding the buffer against an adjacent sash. The invention comprises various details of construction and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claim. My invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which Figure 1 is a perspective view showing the application of niy invention, and Fig. 2 is a sectional view through the device and illustrating the same as applied to a window- 3 5 sash. l i Reference now being had to the details of the drawings by letter, A and B designate. the two sash of a window, and to the former of which a plate C is held by means of screws 0 D or other fastening means, and said plate -'ha's ahandle extension C" thereon, which is adapted to project beyond the face of the sash A and has two lugs E projectin from the top thereof and which carry a pin F upon which the lever H is pifi'oted. One end of said lever has a recess in which is seated a bufier K, and the other end is curved to form a handle N, which may be gripped with the handle extension G when it is desired to tilt B. A screw is fitted in a threaded ape ture in the lever H and is adapted to bear against the upper surface of the plate C for the purpose of lockin the buffer at the end 0'0 of the lever frictionaly against said sash B, and amille'd head R is formed at one end of said screw R. I

From the foregoing it will be observed that by the provision of the locking device shown and described a simple, and efficient means is afforded whereby either the u per or lower sash may be held in different ocations and securely locked by the tightening of the screw R. What I claim is- In combination with the upper and lower sash of a window, a plate secured to the to I of the lower sash and provided with a hand ev which is slightly downwardly curved and ex- 7 tending beyond one face of the sash to which it is secured, lugs rising from said plate, a pin mounted in apertures in said lugs, a lever pivotally mounted upon said pin and having one end thereof recessed, a buffer seated in' & said recess, a spring interposed between the lever andthe bottom of the plate intermediate said lugs, an adj Listing-screw passing through a threaded apertiue in said leverand adapted to bear against the plate, the outer end of said lever forming a handle which is slightly concaved and adapted to be gripped with the handle of said plate when it is desired to release the lever from contact with a window and raise the latter, as set 9 forth. g In testimony whereof I hereunto affix my signature in the presence of two witnesses.
